3D printers are the future, check out this awesome gear assembly

CES 2013 - There are several manufacturers showing off 3D printers and 3D printing technology at CES this year, and while walking the floor I saw the following gear assembly that was printed as a single print.

While printing something like this isn't possible at home quite yet, 3D technology is definitely coming along nicely and we should hopefully be able to do prints like this at home soon. The device is fully functional, as you can see in the video, which is just absolutely incredible!
